According to the Contract Law, this contract is signed by both parties on the basis of equality, voluntariness and consensus, with specific performance contents and termination date. If the termination date is not reached or there are other conditions to terminate the contract, the word "invalid" alone cannot prove that the contract is invalid. I suggest that you ask a lawyer to provide legal help when you are in trouble!
